any chance you could look into the GW .dat format? I'd post a link to one of the archives, but you only have one archive which is the entire install and mine is currently 200+ megs. but if youd like to dl the client (93 kb) ill lend one of the admins my acct to get a small archive

Ok, check out my preliminary specs at the Work In Progress page of Guild Wars at the XeNTaX WIKI.

Please let your gang join up and help figure it out there!

gw.dat decompression.
decompression easy, extraction harder.
gw.exe -image to download the decompressed gw.dat
I also refer you to my post on this thread: viewtopic.php?t=1645&postdays=0&postord ... s&start=15
Which has a similar discussion.

Try extracting only riff, then open in a wave editor like cooleditpro. I found this way with FACTIONS preorder client, using extractor 2.4. I found a good 22050 wave file between noise when opening a riff, then just edited out, saved as pcm wave.

Found a very interesting zip file!
Found a very interesting zip file here: ftp://ftp.plaync.com/Source/XDeltaWithNCsoftMods1.zip
This seems to contain information on all of NCSoft compression techniques, hope this is useful to some people.
Edit:-
Some of the sub info points here: http://www.ietf.org/rfc/rfc1951.txt
And that in turn points here: ftp://ftp.uu.net/graphics/png/documents ... index.html
I did notice this however:
Just trying my best to help.

I did notice this however:
So it may possibly be Deflate AKA a combination of the LZ77 algorithm and Huffman coding.RFC 1951: DEFLATE 1.3 specification
Abstract: This specification defines a lossless compressed data format that compresses data using a combination of the LZ77 algorithm and Huffman coding, with efficiency comparable to the best currently available general-purpose compression methods. The data can be produced or consumed, even for an arbitrarily long sequentially presented input data stream, using only an a priori bounded amount of intermediate storage. The format can be implemented readily in a manner not covered by patents.
Just trying my best to help.

I did take a (quick) look at it, but it seems the changes NCsoft made to the source code are rather trivial and have nothing to do with GW.DAT compression (it still is only an XDelta implementation, after all).
Check out the REWiki!
